iPod Touch calendar no longer syncs with Macbook after upgrade to Mavericks
I have a 2nd Gen iPod Touch, running iOS 4.2.1 (the latest available). My MacBook Air previously ran Mac OSX Lion, and would happily sync the calendar with my iPod. I've just upgraded to Mac OSX Mavericks, which apparently comes with iTunes 11.1, but plugging my iPod into the USB port no longer causes the calendar to sync. I've tried manually syncing through the iTunes interface but it simply ignores the calendar, which remains stuck as it was when I last synced.
What am I doing wrong here?
